Choose the right file tool

Use the PDF organizer to combine documents, split pages into separate files or change their order and rotation. Use the image compressor to resize JPG, PNG or WebP images. Use the CSV cleaner to review columns, remove duplicates and prepare a delimited text export.

Need a different document format? Convert Word DOCX to PDF for straightforward documents, or convert text-based PDF to editable Word DOCX. Read each converter’s formatting limits before using the result.

Free calculators

Calculator pages explain their supported dates, assumptions and sources. Estimates are separate from the paid products linked on those pages.

Free, with files kept local

No accounts, paid credits or uploads. Each tool explains its file limits and formatting behavior. Processing uses your device’s memory and CPU, so smaller batches work better on phones. Downloads are separate copies; keep your originals.
